Why Is It?

So tell me, why is it that when your husband works on computers all day the ones at home are the ones that never work? Is it just the fact that by the time he gets home his brain is just work overloaded and fried and he is just too mentally fatigued to figure it out? Everytime I finally get used to something new he has changed or adjusted something else suddenly goes wrong. WHY IS THAT? Last night he installs a security setting on our wireless network so no cheapskates can mooch off of our internet. Great idea right? Hmph! So why is his computer working just fine but I can't log onto the internet with mine? The security is so wonderful you can't connect on the same network let alone outside of the network. Oh well, I got a temporary fix until he can focus on it to make it right. Until then it is a crap shoot to see if it will work each time I log on. I just LOVE technology. Supposed to make our lives easier............
